Title
(EN) METHOD AND DEVICE FOR EMITTING A LASER BEAM IN A HOUSING
(FR) PROCEDE ET DISPOSITIF D'EMISSION D'UN FAISCEAU LASER DANS UN BOITIER
Abstract
(EN)
The invention relates to a device for emitting a laser beam, which comprises, in a housing (320): a component (345) emitting a laser beam and being mounted on a base (305); a heat-dissipating component (330) for dissipating the heat produced by the laser of the laser-emitting component and to which the base of the emitter component is secured, the heat-dissipating component having a positioning mark (310) and at least three holes for centring pins machined together with the positioning mark; at least one collimating lens (365); and a lens mounting (335) suitable for holding said lens opposite the component emitting the laser beam, said lens mounting being positioned relative to the heat-dissipating component by means of at least three centring pins (315) positioned in the holes of the heat-dissipating component.
